TT: How are winch-ropes developed by your organisation proving to be a substitute for steel-wire ropes and in what all applications?

The Plateena ropes are made with Dyneema and have the same strength and diameter as a steel wire rope with only 1/7th to 1/5th of the weight. These ropes do not need any oiling or greasing thus saving precious manpower and avoiding down time. Since no oil or grease is to be applied it does not contaminate the sea water thus is environment friendly. It is soft on hand and does not cut it. It does not snap back thus leading to better safety on – board the fishing vessel. The ropes are used as a replacement to SWR for fishing, shipping and power line erection. Though the winches for these applications are different; different versions of Plateena ropes are designed for each application.

TT: What is an aquaculture cage and what is the technology used in producing the same?

An aquaculture cage is a bag wherein fishes are grown in captive condition by feeding various types of fish meal. The fish in wild catch is reducing and is not sufficient for the growing population. Therefore, this type of fish breeding helps providing the protein rich food to the masses. Traditionally Aquaculture cages are made of Polyamide and in the recent past from Dyneema knotless nettings and in some cases knotted nettings. However, Polyamide cages attract lot of fouling and require antifouling coating to be done which is environmentally hazardous. Cages made with Dyneema are very costly. GWRL has recently developed a new Polyolefin Multi-Mono filament called STAR. This enables making of cages without anti fouling coating and at the same time not exorbitantly costly. Due to no anti-fouling coating the fish produced are organic in nature (without traces of copper etc.)

TT: What are the benefits of using UV-stabilised nets in agriculture and how do they prove useful?

Nets without UV-stabilization will not last more than 12 months. UV-stabilised nets are designed to last for a period of 3-5 years under local conditions. These offer better value for money to the customers due to extended life.
